[The specific dermatoses of pregnancy].

The specific dermatoses of pregnancy represent a heterogeneous group of inflammatory skin diseases related to pregnancy and/or the postpartum period. The most recent classification includes pemphigoid gestationis, polymorphic eruption of pregnancy, intrahepatic cholestasis of pregnancy, and atopic eruption of pregnancy. The hallmark of all four entities is severe pruritus that is accompanied by characteristic skin changes. While some of these dermatoses are distressing only to the mother because of pruritus, others may be associated with significant fetal risks. Early diagnosis and prompt treatment are therefore essential. In this review, we will discuss the various pregnancy dermatoses in detail and present an algorithm for diagnosis and management of pruritus in pregnancy.
